为android的plugin框架提供注解开发支持
- 高度扩展
- 注解开发
- 轻量化
- 在onCreate中调用Plugin.inject(this)
- 开发类
- After 在某个注解执行之后执行，可用于多个注解时的排序，比如BindFragment需要在Views之后执行
- 类型(Class)
- ContextView 声明上下文试图
- NoActionBar 声明不使用ActionBar
- 属性（Field)
- BindFragment 将Fragment添加到FragmentTransaction
- Service 生成或获取对象或服务
- Value 获取xml中的资源
- Values 字符占位符解析
- Views 获取试图组件
- 方法(Method)
- AfterInjected 在Plugin的属性类注解执行完之后执行方法
- BindEvent 绑定View的事件，一般用于替换setXXXListener
- Click 绑定click事件
- Drag 绑定Drag事件
- LongClick
- Touch
- Message 绑定消息
- UserHandler 使用Handler的方式调用方法（与Message同时使用可以更新试图）
- Synchronized 修饰 事件类型（包括Click,Drag,LongClick,Touch）用以提供防重复触发事件的功能,需要调用EventContext.completedEvent()去完成事件之后才能再次触发事件
- Plugin.inject(Activity activity) 注入activtiy
- Plugin.inject(Fragment fragment) 注入fragment
- Plugin.inject(Context context,Object instance) 注入一个实例
- ViewsHolder.setContextView(View view) 设置试图解析器的上下文
- Plugin.currentContext() 获取当前的Context
- Plugin.register(Class<? extends Annotation> anno,xxxHandler<? extends Annotation> handler) 注册某一类型的handler
- StringHolder.decodeString(String express) 解析字符表达式
- Plugin.createInstance(Class clazz,boolean injected,Object... args) 创建一个实例，injected为是否需要在创建后立即注入，args为参数
- MessageBus.push() 消息同步推送相关api
- MessageBus.pushAsync() 异步推送消息相关api
- MessageBus.reject() 拒绝接收当前消息
- EventContext.completedEvent() 当一个方法为Click，Drag等调用且使用Synchronized修饰的方式是，使用此方法完成当前事件，否则此类方法只能被调用一次
- 定义注解
- 依据注解类型实现各自的接口
- 通过static代码快注册实现
